Do you wear your favorite (and most basic) bra more often than you care to admit?

If so, according to a recent study by global lingerie retailer, Rigby & Peller, you are not alone. Seventy percent of the 2,000 women ages 18+ surveyed, regularly strap on the same brassiere every day.

To get the scoop on why this is a bad idea and other life changing tidbits about underpinnings, FEMAIL talks to Rigby & Peller's Luxury Lingerie & Swim Stylist, Jennifer O'Connell.

'You should never wear the same bra two days in a row,' says Jennifer.

'This is to preserve the elasticity in the bras. After every wear, you want to give your bra a “rest” to get back into shape.'

The solution? Jennifer suggest rotating (at minimum) three bras. To do this, build a lingerie wardrobe that consists of these five essential styles.

A wardrobe isn't complete with just bras. 'Matching bottoms are also an essential piece to the puzzle,' she says. 'Women tell us all the time how confident they feel when they wear a matching set.'

While everyone wants to get the most bang for their buck, of the 2,000 women surveyed, 30% of them have been wearing bras that they've owned for over 10 years, and 5% admitted to owning at least one bra for over 20 years. Talk about a choicest cost-per-wear ratio!

' This depends entirely on how many bras you have, how often you wear each one, and how well you take care of them, but we recommend replacing your go-to bras at least once a year,' says Jennifer.

Do you wear your bra multiple times and then just toss it into the wash with the rest of your laundry? Bad idea.

'You should wash your bra every 2-3 wears', says Jennifer. 'We recommend washing it with a lingerie specific soap, as these washes are designed to protect the elastic and are very gentle on delicate fabrics.'

According to the study, US women prioritize comfort above all else and 80% of the respondents have at least one bra that they find 100% comfortable but not beautiful.

Ready to begin shopping for fall? 'The most important thing to start with is a bra that fits you beautifully and makes you feel confident,' says Jennifer. So ditch your tired old intimates and start a new – it's what's on the inside that counts!
